The deep sea is the oldest and largest biome on Earth, yet we have little knowledge of the ecosystems and processes in these dark, hidden depths. Only in the last two decades have new technologies enabled scientists to start exploring this last frontier – and their discoveries are fascinating but alarming: the deep sea is teeming with life but is already showing clear signs of anthropogenic impacts despite its remoteness. Many vulnerable deep-sea habitats and communities are being destroyed by fishing and are under threat from increasing exploitation of their mineral and living resources.Resource Type: Reports

Technical report on the collection of geographic data, the regression analysis of explanatory factors of land use patterns, the development of a set of three alternative scenarios, and the modelling of land use changes using the CLUES model. This work was carried out as part of the ICRAN-MAR project's sub-result 1.2, "Trends in land use integrated with spatial, hydrological and oceanographic models for use in modelling".Resource Type: Reports
This synthesis focuses on estimates of biodiversity change as projected for the 21st century by models or extrapolations based on experiments and observed trends. The term “biodiversity” is used in a broad sense as it is defined in the Convention on Biological Diversity to mean the abundance and distributions of and interactions between genotypes, species, communities, ecosystems and biomes. This synthesis pays particular attention to the interactions between biodiversity and ecosystem services and to critical “tipping points” that could lead to large, rapid and potentially irreversible changes. Comparisons between models are used to estimate the range of projections and to identify sources of uncertainty. Experiments and observed trends are used to check the plausibility of these projections. In addition we have identified possible actions at the local, national and international levels that can be taken to conserve biodiversity. We have called on a wide range of scientists to participate in this synthesis, with the objective to provide decision makers with messages that reflect the consensus of the scientific community and that will aid in the development of policy and management strategies that are ambitious, forward looking and proactive.Resource Type: Reports
The third edition of Global Biodiversity Outlook (GBO-3) summarizes the latest data on status and trends of biodiversity and draws conclusions for the future strategy of the Convention. GBO-3 is based on a range of information sources, including National Reports, biodiversity indicators information, scientific literature, and a study assessing biodiversity scenarios for the future.Resource Type: Reports
The Global and Regional Assessments of the Marine Environment Database (GRAMED) has been developed at the request of UNEP and IOC/UNESCO, as the lead agencies responsible for taking forward the "Assessment of Assessments" through the implementation of UNGA Resolution 60/30. It was first developed to support the preparation of the 2007 report, Global Marine Assessments: A survey of global and regional assessments and related scientific activities of the marine environment and builds on the 2003 UNEP-WCMC/UNEP/ IOC-UNESCO report "Global Marine Assessments: A survey of global and regional marine environmental assessments and related scientific activities".Resource Type: Tools / Applications
The Global Island Database aims to enhance the participation and role of islands in international decision-making through identifying and bringing together existing sources of data and information relevant to island systems, and presenting new analyses to aid resource managers and decision-making at the island, national, regional, and global level.
The GID also aims to develop linkages, partnerships and collaborations with the wide array of organisations involved in island conservation and decision-making to ensure that the database is up-to-date and relevant, and so it provides a platform for communication and networking.Resource Type: Tools / Applications
Economic valuation of marine and coastal ecosystem services is increasingly being considered to be of critical importance for informed decision-making and effective management of marine and coastal resources.
However, the translation of scientific theory to policy in practice can be challenging.
This report provides an overview of the main methods of economic valuation, their strengths and weaknesses, and practical applications. Theoretical concepts are illustrated with a number of practical examples throughout this report, to demonstrate how these approaches can be of practical use across all scales, in policy development, decision making and communication. Practical guidance on how to implement a valuation exercise, and how to overcome common challenges, is also provided.
UNEP-WCMC has been working closely with partners including the CBD Secretariat to implement COP Decision IX/20, to develop an online interactive map and associated tools to support decision making for the conservation and sustainable use of biodiversity in the open ocean and deep seas. Building upon this decision, and incorporating related needs in the Island Biodiversity and Protected Areas Programme of Work, UNEP-WCMC has initiated a collaborative Global Marine Data Partnership, whose aim is to:
These activities directly respond to SBSTTA recommendation XIV/3, which will be considered by COP10, through, inter alia, enabling improved assessment activities, supporting the identification of ecologically or biologically significant marine areas (EBSAs), and promoting better understanding of specific and cumulative human impacts, including those of invasive alien speciesResource Type: Tools / Applications
On behalf of the CBD Executive Secretary, UNEP-WCMC has compiled and synthesized available scientific information on ocean fertilization and its observed and predicted impacts on marine biodiversity and habitats. The study will inform the review of the CBD marine and coastal programme of work in 2010.Resource Type: Reports
